BUILDING-BRICK.

I Specification of Letters Patent.

Patented Dec. 2, 1919.

Application filedNovemberZ'Y, 1918. Serial No. 264,305.

To all whom it may concern:

Be it known that 1, JOHN J. VVHITACRE, a citizen of the United States, and a resident of Canton, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Bulldmg- Bricks, of

. 'which the following is a'specification' The invention relates to-ribbed bricks for building walls with air channels, and the object of the improvement is to make a brick with ribs or projections on one side only of" a bed or body plate, which may be laid 1n a wall with interlocking joints of mortar.

A further object of the mvent on is to make a wall with a continuous longitudinal air channel in each course of bricks, which not only separates the brick material com prising the lnner and outer faces of the wall,

but also separates the corresponding mortar I joints and prevents the form-atlon of a con tinuous layerv or bed of mortar to carry water or moisture from the outer to the inner portions of the wall.

The objects ofthe invention thus set forth in general terms; are attained by making and marketingthe brick in the form of a hollow block having side walls and two or I more partitions longitudinally weakened along'a median line for ready separation at the place of use into bricks having bed or brick; and by providing an upstanding rib of brick material in each mortar" channel to divide and partially fill the mortar channel, with the usual longitudinal grooves in the bottom of the brick for interlocking with the mortar of the joint.

A preferred embodiment of the invention thus generally described, is illustrated inthe accompanying drawings forming part hereof, in which- T Figure 1 is an end view showing a hollow block cutfor breaking into bricks;

Fig. 2, an end section of an eight inch wall made withthe improved bricks;

Fig. 3, a section of a twelve inch wall embodying the present invention;

Fig. 4, a perspective viewof a brick for making an eight inch wall; and

Fig. 5, a perspective view showing the method of building awall with the ribbed bricks and ordinary corner bricks.

Similar numerals refer to siinilargparts throughout the drawings.

As shown in Fig. 4, each brick for an eight inch wall ismade with a bed or body plate 1 extending in width continuously from the inner to the outer faces 2 and 2 formed by the inner and outer upstanding ribs 3 and 3, of the brick, within which ribs are spaced the upstanding partition ribs 3 forming a mortar channel 4: along each side of the brick and a longitudinal air channel 5 in the median portion thereof.

In each mortar channel is provided a longitudinal upstanding rib 6 intermediate the face and partition ribs and preferably made slightly shorter than the same; which rib dlvides and partially fills-the channel and serves to reduce the amount of mortar required to fill the same, and also. increases the bearing strength of'the bricks along the mortar joints thereof.

The bottom and inner faces of the bricks are provided with the usual longitudinal grooves? and 7* for engaging the mortar or plaster 'used in the building of a wall; which grooves may be dove-tailed in the usual manner; and theouter face 2" of each brick is. preferably made about eight inches long with a depth of two and three-eighths inches so that the brick may be laid fiatwise in a wall and will present afacec'orresponding to the ordinary standard brick, with which it may be combined in the construction of a wall.

The bricks are also preferably made either eight inches or twelve inches, or some other multiple of fourinches in widtlnso as to form an eight inch wall as shown in Fig. 2, or a twelve inch wall as shown in Fig. 3; in which latter event, an additional pair of partition ribs 3 with an intervening filler rib, 6, may be provided along the median line of the brick, so as to increase the strength of the wall and provide an additional mortar joint along the middle thereof.

In the construction of a wall, the bricks are laid with their bed or body plate downward, and mortar is applied to the tops of the upstandingribs and fills more or less of the divided channel 4 at the sides of the filler rib. A sufficientamount of mortar is used to form a suitable layer on the tops of the ribs and to enter the longitudinal groove 7 in the bottom of the superposed brick, so

as to form an interlocking mortar joint '8 Wall. A similar joint may be provided along the median line of a twelve inch I -the brick opposlte the mortar-channels I therein.

Wallas shown in Fig. 3.

The mortar joint 8 however is notv continuous through the wall, and does not extend across the air channel5; and it is evi dent that, any Water ormoisture Which'may run or seep along the mortar joint, from the outer face of the Wall, Will be trapped, first in thebottom of the divided mortar channel located outside the filler rib and neXtinthe divided mortar channel located inside the filler rib, before such water or moisture can reach the air channel in the median portion of the brick; and itis also evident that no Water or moisture can pass beyond, the air-- channelfi so as to affect the inner portions of the Wall, and much less'the innerface formed by the inner ribs of the brick.-

I claim: c l

1. A brick comprising a continuous bed or body plate'havingupstanding side and partition ribs forming mortar channels along each side and anair channel'in the median portion of the brick, and having; an upright :rib in each mortar channel dividing and partially filling the same.
